If the air-ship is desired to be propelled in the opsteering device, the body of the air-ship being made of elongated shape; and Figs. 3 and 4 posite direction, pipes 2 3 6 are opened, and are a side view and a plan of this improved the pipes 1 4 5 closed, the steering to either side being accomplished by the closing of pipe 2 or 3, as required.

In the air-ship'shown in Figs. 3 and 4 the pipes O l 2 3 are open when the balloon is filled with hot air. In ascending or descending, one of the pipes is closed, and the heated air allowed to escape through the remaining pipes to the outside, whereby the air-ship is propelled in the direction of the closed pipe, and steered to either sideby closing one of these pipes until the balloon has, received the proper direction.

The lowerconically-tapering part, A, of the air-ship is provided with pipes 6, provided with valves e, connected by actuating-cords c with the car, so that a greater or lesser quantity of air is admitted tot-he inside of the balloon, and cause thereby the descending or ascending of the same, as has been fully set forth in the Letters Patent N 263,397 heretofore mentioned.

Having thus describedmy invention, I claim as new and desire to secure by Letters Patent 1. An'air-ship having the lower-part of its body conically-tapered toward its bottom, and provided above the tapered part with horizontally-projecting valved pipes for the discharge and regulation of heated air, whereby the air-ship may be propelled and steered in either direction, substantially as described.

2. An airship the body of which is provid- Siinilar letters of reference indicate corresponding parts.

A in the drawings represents the round or elongated body of iny improved air ship, which is made of a light supportingframe of corresponding shape, and of a light covering fabric that is rendered fire and water proof by treatment with chemical substances suitable for this purpose. The lower part of the body A is provided with a comically-tapering downwardly-extending portion, A, within which the means by which the air in the body A is heated are arranged.

The car B is suspended by cords b from the stiffening-frame a, at the lower end of the frame a the strands of the covering-netting of the body A are applied.

At the middle part of the body A are arranged horizontal projecting pipes G C, of. which, preferably, six or more are used when the body is made of elongated shape, as in Fig. 2, the pipes being arranged one at each end and two at each side, while when a round form of body A is used, three or more projecting pipes, G, are arranged, which extend radially at an equal distance from each other, as shown in Fig. 4. The pipes O O are provided with valves d, of any suitable construction, which are openedor closed at will pipes G l 4 5, Fig. 2, are
